What happens to a moving object if NO unbalanced force acts upon it?
It eventually slows down and comes to a stop.
It speeds up in the direction of motion.
It will eventually change direction.
It continues to move at the same speed.
Answer:Newton's first law of motion indicates that an objects motion or lack of motion will stay the same unless acted upon by an unbalanced force.
Explanation:
If your hammer develops a loose head, you can tighten it by banging
it on the ground. A little physics secret though - it's better to bang
the hammer head up rather than head down. Explain, using inertia.
weight from the hammer head makes the inertia better making it better with the head up it. the body has less weight the inertia force isn't as good. (or something like that.)

Ti3N + MgO → Mg3N2 +Ti2O balance chemical equation
We have that the balanced chemical equation is mathematically given as.
2Ti_3N + 3MgO → Mg_3N_2 +3Ti_2O
From the question we are told
Ti3N + MgO → Mg3N2 +Ti2O balance chemical equation.
Generally the way to balance an equation is by making all elements present on the Left hand side(LHS) same with the right hand side RHS.
Therefore
The equation is mathematically given as.
Ti_3N + MgO → Mg_3N_2 +Ti_2OWe consider the Left hand side(LHS) first.
2Ti_3N + 3MgO → Mg_3N_2 +Ti_2OThen we consider the right hand side RHS.
2Ti_3N + 3MgO → Mg_3N_2 +3Ti_2OTherefore the balanced chemical equation is mathematically given as.

During hypnosis, people:
A. can accurately recall memories of early childhood and infancy.
B. lose all awareness of their surroundings.
C. temporarily suspend their sense of initiative.
D. are in a deep trance, which is similar to stage 3 NREM sleep.
During hypnosis, people temporarily suspend their sense of initiative. Hence, option (C) is correct.
What is hypnosis?
According to one definition, hypnosis is "a waking state of awareness, (or consciousness), in which a person's attention is diverted from his or her immediate surroundings and is consumed by interior experiences such as feelings, cognition, and images." In order to induce hypnosis, the subject must concentrate and become sufficiently absorbed in their imagination. A hypnotic world is created by the physician and patient through the use of suggestions and their acceptance.
Our everyday 'trance' states include things like becoming lost in a good book, driving down a familiar route without being aware of it, being in prayer or meditation, or engaging in a mindless or creative task. Our conscious awareness of our surrounds and an inner awareness exist on a continuum, thus even though one's emphasis is mostly internal in these states, one does not necessarily lose all awareness of the outside world.

When the sun heats up the suface of the water, the water
Answer:
In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.

A 65 kg diver stands still on a tower, 100 m above the water
(a) Calculate the gravitational potential energy of the diver, relative to the height of the water. Assume the gravitational field constant is 9.8 N/kg
(b) The diver reaches the surface of the water at a speed of 14 m/s. Calculate the diver's kinetic energy
(c) Compare your answers to (a) and (b). Explain your comparison using concepts learned in this course.
Assume there is no air resistance during the dive (d) Calculate the speed of the diver 5.0 m above the water.
Following are the solution to the given points:
Given:
[tex]\to mass(m)= 65\ kg\\\\\to h=10.0 \ m\\\\\to g=9.8 \ \frac{m}{s^2}[/tex]
To find:
gravitational potential energy(GPE)=?
kinetic energy(KE)=?
concept=?
v=?
Solution:
For point a:
[tex]\to GPE= mgh[/tex]
[tex]= 65 \times 10 \times 9.8\\\\ = 6370 \ J\\\\[/tex]
For point b:
[tex]\to KE=\frac{1}{2} m v^2\\\\[/tex]
[tex]=\frac{1}{2} \times 65 \times 14^2 \\\\=\frac{1}{2} \times 65 \times 14 \times 14 \\\\= 65 \times 14 \times 7 \\\\=6370\ J\\[/tex]
For point c:
As we've seen, there really is no force acting, and the mechanic KE: GPE is used. Because legitimate is conserved. Home energy loss means GPE must be equal to KE gain.
For point d:
A diver has risen 5 feet above the surface. As a result, according to the energy conservation law:
[tex]\to U_i + K_i= U_f + K_f\\\\ \to mg \times h + 0 = mg \times \frac{h}{2} + \frac{1}{2} m v^2\\\\ \to 9.8 \times 10 = 9.8 \times 5 + \frac{v^2}{2}\\\\\to 9.8 \times 10 - 9.8 \times 5 = \frac{v^2}{2}\\\\\to \frac{v^2}{2} =9.8( 10 - 5) \\\\\to v^2 =9.8( 10 - 5) \times 2 \\\\\to v^2 =9.8\times 5 \times 2 \\\\\to v^2 =98 \\\\\to v =98\ \frac{m}{s^2} \\\\[/tex]

A machine has an efficiency of 15% . If the energy inputs is 300 joules, how much useful energy is generated
Answer:
you made with your performance, and then consider whether you would do anything differently if yo
Explanation:
The useful energy generated by the machine having an efficiency of 15% and an energy input of 300 J is 45 J
From the question given above, the following data were obtained:Efficiency = 15% = 0.15
Work input = 300 J
Work output =?The useful energy generated (i.e work output) by the machine can be obtained as follow:
[tex]Efficiency = \frac{workout}{workin} * 100\\\\0.15 = \frac{Workout}{300}[/tex]
Cross multiply
Work output = 0.15 × 300
Work output = 45 JTherefore, the useful energy generated by the machine is 45 J

d = (vx₀)t
t = d/vx₀
horizontal analysis
0 = vy₀t + ½gt²
0 = vy₀(d/vx₀)+ ½g(d/vx₀)²
as vy₀ = v₀sin45 and vx₀ = v₀cos45 and are equal.
0 = d + ½g(d²/v₀²cos²45)
-d = ½g(d²/v₀²cos²45)
-dv₀² = ½g(d²/cos²45)
v₀² = -½g(d/cos²45)
v₀² = -½(-9.81(32.0/cos²45)
v₀² = 313.92

When a Cellulose Acetate rod is rubbed with a woolen duster, friction occurs, rubbing loosely held electrons from the rod onto the duster. So, this time, the rod loses electrons. Since the Acetate rod now has fewer electrons than protons it has become positively charged. Hope this helps!
Answer:
The charge becomes positive.
Explanation:
When rubbed with cellulose acetate the charge of the fur/wool will become negative.
